Bush Clover vs Obedient Plant Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Bush Clover
Lespedeza spp.
Bush clovers are a diverse group of herbaceous perennials or subshrubs, typically characterized by their trifoliate leaves and pea-like flowers. They range in height from a few inches to several feet, depending on the species. Many species are valued for their drought tolerance and ability to thrive in poor soils, making them useful for erosion control and wildlife habitat. While some species are considered invasive in certain regions, others are cultivated for ornamental purposes or forage. They are primarily outdoor plants and do not thrive indoors.
Obedient Plant
Physostegia virginiana
Physostegia virginiana, commonly known as Obedient Plant, is a herbaceous perennial native to North America. It's characterized by its upright growth habit and lance-shaped, toothed leaves. The plant produces spikes of tubular flowers in shades of pink, lavender, or white during late summer and early fall. It gets its name from the fact that if you gently bend the flowers on the stem, they will stay in the position you put them, hence 'obedient'. Primarily an outdoor plant, it's grown in gardens for its late-season blooms and attractiveness to pollinators. Indoor cultivation is challenging due to its high light and space requirements.

❓ Frequently Asked Questions — Comparing These Plants
Bush Clover
What are the light requirements for Bush Clover?
Bush Clover requires at least six hours of direct sunlight per day for optimal growth and abundant flowering. While it can tolerate partial shade, insufficient sunlight can lead to leggy growth and reduced bloom production. In hotter climates, some afternoon shade can be beneficial to prevent scorching of the foliage. When planting Bush Clover, choose a location that receives ample sunlight throughout the day. If growing in containers, rotate the plant regularly to ensure even light exposure on all sides. Monitor the plant’s growth and adjust its location as needed to provide the appropriate amount of light. South-facing locations are generally ideal.
How do I care for Bush Clover?
Bush Clover thrives in well-draining soil and requires full sun to partial shade for optimal growth and flowering. Water regularly, especially during dry periods, but avoid overwatering, which can lead to root rot. Fertilize in early spring with a balanced fertilizer to promote healthy growth and abundant blooms. Prune annually in late winter or early spring to remove dead or damaged branches and to maintain the desired shape. Bush Clover is relatively drought-tolerant once established. Protect from extreme cold in colder climates with a layer of mulch around the base of the plant. Monitor for pests and diseases, and treat promptly if necessary. Provide support for taller varieties to prevent them from sprawling. Ensure good air circulation to prevent fungal diseases. Regularly check the soil moisture to ensure proper watering.
How do I propagate Bush Clover?
Bush Clover can be propagated through several methods, including division, stem cuttings, and seed. Division is best done in early spring or fall. Carefully dig up the plant and divide the root ball into smaller sections, ensuring each section has healthy roots and shoots. Replant the divisions in well-draining soil. For stem cuttings, take 4-6 inch cuttings from new growth in late spring or early summer. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cuttings in a moist, well-draining potting mix and keep them in a humid environment until they root. Seeds can be sown in early spring after stratification (cold treatment). Keep the soil moist and warm until germination occurs.
Obedient Plant
What are the light requirements for Obedient Plant?
Obedient Plant thrives best in full sun, requiring at least 6 hours of direct sunlight per day to produce abundant blooms and maintain strong, upright growth. In hotter climates, some afternoon shade can be beneficial to prevent leaf scorch. Insufficient sunlight can lead to leggy growth, reduced flowering, and weaker stems. When grown indoors, place Obedient Plant near a sunny window, such as a south-facing or west-facing exposure. Rotate the plant regularly to ensure even light exposure on all sides. Supplemental lighting may be necessary during winter months or in areas with limited natural light.
How do I care for Obedient Plant?
Obedient Plant thrives in full sun to partial shade and prefers moist, well-drained soil. Water regularly, especially during dry periods, but avoid overwatering to prevent root rot. Fertilize in early spring with a balanced fertilizer to promote healthy growth and abundant blooms. Deadhead spent flowers to encourage further blooming. Be aware that Obedient Plant can be aggressive; consider planting it in containers or using barriers to control its spread. Prune back stems after flowering to maintain shape and prevent excessive self-seeding. Monitor for pests like aphids and spider mites, and treat as needed. Provide adequate air circulation to prevent fungal diseases.
How do I propagate Obedient Plant?
Obedient Plant can be easily propagated through division, stem cuttings, or seeds. Division is best done in early spring or fall by separating the rhizomes and replanting them. For stem cuttings, take 4-6 inch cuttings from healthy stems in late spring or early summer. Remove the lower leaves and plant the cuttings in moist potting mix. Keep the cuttings humid by covering them with a plastic bag or dome. Seeds can be sown directly in the garden in fall or started indoors in early spring. Keep the soil moist until germination.
